JAMES L. RECORD, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF ONE-HALF I TOJOSEPH GARRETT, OF SAME PLACE.

HORSE-POWER.

SPECIFICATION forming part of Letters Patent No.368,970, dated August30,1887.

Application filed March 28, 1887.

To all whom it may concern.-

Be it known that I, JAMES L. REooRD, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in Horse-Powers, of

which the. following is a specification.

My invention relates particularly to horsepowers for heavy work when twoor more horses are used; and it consists, generally, in a mas- 1otor-wheel operated by the sweep and meshing with two pinions on twoseparate shafts running radially to the master-wheel, these shafts beingprovided at their inner ends with bevel-gears, which mesh with a pinioncommon to both upon the main power-transmitting shaft. By

this means I am enabled to distribute the strain more equally upon themaster-wheel and upon the pinion of the main transmitter-shaft, and alsoto increase the speed of the said shaft.

My invention further consists in the construction and arrangementhereinafter described, and particularly pointed out in the claims.

In the drawings, which form a part of this 2 5 specification, Figure 1is a central vertical section 011 the line of the two counter-shafts.Fig. 2 is a vertical section on a line with the main or power shaft.Figs. 3 and 4 are details showing the construction of the step and shaftbearingS.

In the drawings, 2 represents the frame of the machine.

4 is a step-casting centrallylocated and supported upon suitable timbersof the frame 2. 5 This casting is preferably made as shown in Figs. 3and 4, having bearings 5 for the horizontal shafts, and also abearing,.6, at right angles to the bearing 5, which supports the innerend of the main power-shaft. These three bearings are on the samehorizontal plane, and are provided with suitable caps and bolts, and areconnected by the plate 7, which also forms a support and means forattachment to the frame. The step or vertical bearing 9 for the piecemaster-wheel shaft is also formed in one with the horizontal bearings.

Vertical plates 8 extend downward from the plate 7 on the inside-of theframe-timbers, and are connected by the bridge 10, upon which Serial No.232,691. (No model.)

the step is formed. I prefer to form these bearin'gs in one piece,'forconvenience in construction and to assure their being kept in line.

15 is a vertical shaft resting in the step and held in position by andrevolving in suitable bearings, 17, upon the frame.

18 is a master-wheel hung upon the shaft 15 and revolving with it.

20 are pinions diametrically opposite each other, the teeth of whichmesh with the teeth of the master-wheel.

The pinions 20 are hung upon countershafts 21, which revolve in bearings5 and 22 upon the frame. These shafts are set radially to the shaft ofthe master-wheel, and upon their inner ends are secured the bevel-gears24. These gears may be made of any suitable size to give the requiredspeed. The pinion 25 upon the main or power shaft 26 is common to boththe gears 24, which are arranged to mesh with the said pinion uponopposite sides. The shaft 26 revolves in the bearings on the step orcenter casting, and may be provided with other bearings necessary forits support.

The sweep-head 30 is located at the upper end of the shaft 15 in theordinary manner.

Bearing-wheels 31 may be placed above the pinions 20 and arranged tobear upon the master-wheel for the purpose of keeping it steady.

The operation is as follows: Power is applied to the sweeps attached tothesweep-head, and by this means the shaft 15 and the masterwheel arerevolved. This imparts motion to the pinions 20, together with theshafts 21 and bevel-gears 24, attached thereto. The opposite shafts,being driven from opposite sides of the master-wheel, will revolve inopposite directions; but this motion is again brought to act in the samedirection by the pinion 25,.

which is common to both gears, and upon the opposite sides of which theymesh. It will be seen that by this arrangement a double contact is madewith the master-wheel, thus balancing the machine and relievingthestrain by onehalf, or allowing double the amount of power to betransmitted with the same strain as compared with the machine using asingle pinion. The same benefit is derived in transmitting the powerback to the main shaft. The gears, actthe gears 20, meshing with themaster-wheel,

and upon their inner ends with the bevel-gears 1 5 24, and thepower-shaft 26, mounted in said bearing 6, and provided on its inner endwith the bevel-gear 25, meshing with both of said gears 24,substantially as described.

In testimony whereof I have hereunto set 20 my hand this 18th day ofMarch, 1887.
